IMPROVEMENT IN MACHINES FOR BENDING AND FORMING ST IFFENERS FOR BOOTS AND SNOES.

Specification forming part of Letter s Patent No. 155,071, dated September 15,1874; application filed July 1, 1874.

To all whom it may concern:

Be it known that I, LoUIs COTE, of the city of St. Hyacinthe, in the county of St. Hyacinthe, in the Dominion of Canada, have invented a Machine for Bending and Forming Stiffeners for Boots or Shoes, of which the following .is a specification:

The nature of my invention consists in fixing upon a rotating shaft a mandrel of a spheroid or sphero-cylindrical shape, and under it an annular rotating and elastic matrix, so that by being strongly pressed together and turning in inverse directions they may, by their joint action, shape, bend, and permanently form pieces of leather or composition to be used as stifl'eners for boots or shoes.

Figure 1 is a side elevation of the machine. Fig. 2 is a front perpendicular section of the mandrel and matrix through their periphery.

A, frame bearing the working parts; a, cross-pieces to join the end parts of the frame a adjustable cushion bearing upon the mandrel-shaft so as to press, as required, the manwhich the matrix-wheel is fixed.

geared or toothed Wheel, W, of the same diameter as the matrix-wheel, or nearly so. The shaft rotates in bearings fixed to the frame A. C, mandrel. It is a spheroidal or sphero-cylyndrical piece of metal fixed upon the shaft 0. c is a pinion fixed at the same shaft. It receives its motion from the fixed belt-pulley 0 or in any other convenient way. 0 is a loose pulley to stop the machine when required. The pinion 0 gears into the Wheel b and gives it and through it to the matrix-wheel a rotary motion, so that the surface of the mandrel and that of the matrix move together at an equal velocity, or nearly so.

The operation of the machine is simple, and any one familiar with the art will understand how a piece of leather or other substance of like nature, of suitable size, when placed near the mandrel and matrix, will be drawn be tween them by their rotation, and during its passage will receive a double curve corresponding to that of the end of the mandrel.

What I claim as my invention is- The matrix-wheel B, provided with an elastic periphery, b, in combination with the mandrel C, all constructed and operating substantially as and for the purpose as hereinbefore set forth.

LOUIS COTE.
